Bed BugsAlterative Treatments By Dan McCabe Vice President Magical Pest Control dan@magicalpest.ca
Treatment Methods • Spray and dust treatments • Steaming • Cryonite • Heat
Obstacles • Poor Preparation • Refusals • Not reporting a problem • Chemical resistance
Pros No pesticides Resident only needs to be out for as long as the job takes Cons More costly/labour intensive Full prep is required Steaming/Cryonite
CryoniteHow Does it work? • C02 (carbon dioxide) • Thin layers applied as dry ice snow • -110F • 3 particle sizes (sm,med,lrg) • Freezing of fluids in cells • Has a wider treatment band
CryoniteEfficacy Tests • Insect Investigations Ltd • Recognized by Department of Agriculture UK • 10 adult, ten nymph, batch of eggs between 10-50 • Applied as four short bursts • 3 separate tests • Cardboard was placed in tank to simulate crack/crevices
CryoniteSummary • 1st test 100% kill of all stages • 2nd test 90% kill of all stages • 3rd test 100% kill of all stages • Eggs were observed for 7 days, none hatched
Pros No pesticides One treatment 100% kill Purifies air No preparation No laundering of clothes Cons Possibly more expensive Tenant needs to away for the day Heat Treatment

Experts Agree • “The heat process provided an effective non-chemical alternative to conventional pest control.” Dr. Michael K. Rust, Ph.D. past Chair for the Department of Entomology Univ. California, Riverside. • The thermal [heat eradication] method is the best by far for treating an entire structure, and we highly recommend it. This is a completely safe and highly effective nontoxic technology.” Dr. Marion Moses, Physician, author of “Designer Poisons”
Pros Can verify an infestation. Can pinpoint exact locations. Can reduce the use of pesticides. Gives peace of mind. Cons It is not a treatment method. Bed Bug Dogs
Pros Easy to use (doesn’t require a license) Can verify an infestation Inexpensive Gives peace of mind Cons It is not a control method Monitoring Devices
Summary • Conventional spray treatments are still very effective provided we have the resident’s co-operation. • Steaming/Cryonite is a good option. • Heat treatment is the most effective. • Bed Bug Dogs and monitors are a helpful tool.
